mine was ok but it has weakened a little
I am sure they are OK if you are just using it on a desktop and worried about kids, dog, etc. running into the cord. But I tend to like to use my laptop on my lap, and for that it didn't do nearly as well as MagSafe. The newer MagSafe, also didn't do as well for that as the older version imho.
That's what I read about it, guess the search continues for a MagSafe replacement
I should have read more reviews on it, but I had to go to Best Buy for a couple of other purchases, saw it on the shelf, recalled the recommendation, and decided to grab one.
After about 1 hour of mostly failed use, I unplugged it and back it goes. As you say, the search for a MagSafe replacement continues
